SILAS II. RANDALL, OF WYOMING, OHIO, ASSIGNOR OF ONE-HALF TO JAMES D. RANDALL, OF SAME PLACE.

HORSE-COLLAR MOLD.

SPECIFICATION forming part of Letters Patent No. 453,565, dated June 2, 1891.

Application filed December 22, 1890. Serial No. 375,439. (No model.)

To aZZ whom it may concern.-

Be it known that I, SILAs II. RANDALL, a citizen of the United States, residing at W'yoming, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Horse-Collar Molds; and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the annexed drawings, which form a part of this specification.

My invention comprises a machine to which various forms of molds can be readily applied for the purpose of shaping difierent sizes of horse-collars, the details of said machine and the method of operating it being hereinafter more fully described.

In the an nexed' drawings, Figure 1 is a plan of one of my collar-molds detached from the machine. Fig. 2 is a plan of a portion of the bed or table of the machine, the place the mold occupies upon said bed being indicated by dotted lines. Fig. 3 is a sectionized side elevation of the machine, a mold being seen mounted upon said table and a collar in the act ofbeing shaped around said mold. Fig.

4 is a modification of my invention.

Referring to Fig. 1, A represents a mold, which is usually a casting with a raised flange or bearing 13 of the proper shape to form a horse-collar, the mold being preferably pro vided at one end with a hook-shaped lug C and having at its opposite end a short downwardly-projecting stud D. (Seen only in Fig. 4.) Of these molds a number may be provided of different widths and lengths, so as to enable the ready shaping of Various sizes and shapes of collars, which molds are mounted upon a bench or table or bed E, one edge of which has an undercut notch e for the hook C to engage with, while the opposite side of said bed has a stock F secured thereto in any approved manner. This stock has a bearing f pierced to admit free passage of a screw G, which engages with the nut h of a hand-wheel II, the front end of this screw being furnished with transverse arms g g, that rest upon the side plates of the aforesaid stock, as seen in Fig. 2. These arms have fastened to them the ends of a crossed rope 1, adapted to enter the hame-crease of an ordinary horse-collar J.

slacken the rope.

e is a groove or slot in the bed E to admit the stud D.

My machine is operated in the following manner: A mold is first selected of the proper size and shape and is so applied to the table E as-to cause the stud D to enter the groove e, while the hook C engages with the undercut notch e,'thc position of said mold being clearly indicated by dotted lines in Fig. .2. The stuffed collar J is then fitted around the shaping-flange I of mold A, and the rope I is inserted in the hame-crease of said collar, the rope being crossed and its ends secured to the screw-ar1ns g g. Hand-wheel II is now turned in such a direction as to cause the nut 76 to revolve against the bearing f of stock F, and thereby retract said screw, the result of this retraction being to exercise a powerful pull on the rope I and cause the collar to be bent very snugly around the mold.

It will thus be seen that the collar is shaped and the hame-crease finished by the simple act of retracting the screw, and when the collar has remained long enough to retain the desired form said screw is advanced to un- The collar is then lifted 0d the mold, another one applied in its place, and the shaping operation proceeded with, as previously described. The bed or table E may be arranged to support a number of the machines, and the molds can be of different sizes, the stroke of screw G being suificientto compensate for any possible variations in the width and length of horse-collars.

In the modification of my invention seen -in Fig. 4 the mold is both detachable and capable of being adjusted either toward or away from the stock of the machine, the adjustment being effected by providing said mold with a spur a, that engages with either one of a set of ratchet-teeth K, secured to the table or bed E. The opposite end of this mold is grooved longitudinally at a to en gage over a guide 6, projecting rigidly from the bed, and the latter has a series of vertical holes or sockets c' to admit the shank Z of a detachable pin L. This pin can be inserted in either of these holes, according to. the location of the mold. upon the bed, and other holes can be made in the bottom plate of the stock, as seen at f The object of the pin is ICO - lines 1.

I I claim as my invention 1. The combination, in a horse-collar-shaping machine, of a bed E, having a fixed stock Ff, carrying a screw G and turning device H h, a readily-detachable mold A B, having at its widest end a coupling device that engages with said bed and at its narrow end a guide that preserves said mold in line with the axis of said screw, and a rope whose two ends are secured'to the screw, substantially as herein described, and for the purpose set forth.

2. The combination, in a horse-collar-shaping machine, of abed E, having a fixed toothed bearing K and a stationary stock F f, carry ing a screw G and turning device H h, a readily-detachable mold A B, having at lts widest end a spur a, that engages with said toothed bearing K and at its narrow end a guide that preserves said mold in line with the axis of said screw, and a rope I, whose two ends are secured to the screw, all as herein described, and for the purpose set forth.

In testimony whereof I aflix my signature in 3-0 presence of twowitnesses.

SILAS II. RANDALL.
